After staring at the lights on the ceiling "scientists" decide Newton was wrong and Einstein is a clown. How long before they realize the lights in sky are only small bits of plasma a few thousand miles away?
Newton’s Law Of Gravity Was Wrong, Claim Scientists; Target Einstein’s ‘General Relativity’ NextThe world knew the famous law of gravity when an apple fell on Isaac Newton’s head, prompting him to form the earliest theory of universal gravitation. The 17th-century gravitational law is a landmark in physics and has held true up until now. The theory of universal gravity has been dismissed in the study of black holes. Scientists conducted research on a star called ‘S0-2’ which is at its closest to black hole Sagittarius A* (abbreviated to Sgr A*) that lies at the centre of the Milky Way 26,000 light-years away from the Earth. The study put the law of universal gravitation to test and it did not hold true. Not in relation to the black hole at least.
As per new findings, scientists are now placing their bets on Einstein’s theory of general relativity. Albert Einstein and Isaac Newton’s discoveries are pillars of modern physics but, the black hole has put both theories by the legendary physicists to test. The black hole study found that the intermingling of space and time near Sagittarius A* doesn’t comply with Newton’s law. According to professor Andrea Ghez of the University of California, Los Angeles Einstein’s theory, however, found fresh evidence.
“Newton had the best description of gravity for a long time but it started to fray around the edges. And Einstein provided a more complete theory. Today we are seeing Einstein’s theories starting to fray around the edges,”Observations of light from S0-2 prove Einstein’s 1915 theory that describes the law of gravity and the relation to other forces. It proves that what we perceive as gravity is the curvature of space and time. S0-2 has a mass that’s 10 times larger than the sun. It orbits around the black hole in an ellipse taking 16 years for an orbit. Studies found that the star's light escaped the black hole’s gravitaional pull. The black hole’s mass is 4 million times more than the sun’s.
Researchers studied the particles of light that travelled from the S0-2 to the Earth. Einstein had predicted that light finds it harder to resist the black hole’s gravitational pull, expending more photons to escape it. But, scientists think it won’t take long to disprove the long-standing theory as well.
“We can absolutely rule out Newton’s law of gravity. Our observations are consistent with Einstein’s general theory of relativity. However, his theory is definitely showing vulnerability. It cannot fully explain gravity inside a black hole, and at some point, we will need to move beyond Einstein’s theory to a more comprehensive theory of gravity that explains what a black hole is.”Black holes are extraordinarily dense and have gravitational fields so strong that light and matter cannot escape. This is why Einstein’s theory cannot fully explain the way gravity works in and around the black hole. Scientists will soon have to find a much more comprehensive theory that can be applied to the study of black holes. Ghez thinks Einstein is right but, the theory can fall apart too.
The research on S0-2 is co-led by Andrea Ghez is titled ‘Relativistic redshift of the star S0-2 orbiting the Galactic centre supermassive black hole’. The science journal is considered to be the most detailed study on the black hole.
